If I changed config.lb

The PCI 1:0.0 and PCI 1:0.1 will be disabled together.
According to AMD 8111 data sheet, LPC 0x48, only can be disabled the
in second bus by device num, and the three USB share
one device number.
So I guess the code about 0x47 must be there.
Ron and I just dicurssed about the enable/disable mechanism for
amd8111. We are going to implement a slightly better one soon.
Actually, the enable/disable for devices in amd8111 is multiplexed
in amd8111_enable and the device_operation::enable() is directed to
amd8111_enable. We are going to demultiplex this and each devices
has its own "real" enable method.
